What is the effect of thermal energy on the atoms/molecules in a sample of matter?

Anestetic [448]

Answer:

When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.

Each of the following reactions is incomplete. Match each of the following particles with the correct reaction in order to compl

kiruha [24]

Answer:

1. Option A. Beta decay minus 0 -1e

2. Option B. Alpha 4 2He

3. Option A. Beta decay minus 0 -1e

Explanation:

1. 66 29Cu is undergoing beta decay minus since it produces a daughter nuclei having the same mass number and the atomic number increased by 1 i.e 66 30Zn

2. 238 92U is undergoing alpha decay since the daughter nuclei produced has a decrease of 4 in the mass number and a decrease of 2 in the atomic number ie 234 90Th

3. 14 6C is undergoing beta decay minus since the daughter nuclei produced has the same mass number and the atomic number increased by 1 i.e 14 7N

Fog is a cloud that has

Flura [38]

Fog is a cloud that has its base at or near the ground. The answer is letter D. Fog results when atmospheric water vapor condenses to the extent that the new forms, water droplets or ice crystals, become visible. Saturation of the air and sufficient condensation nuclei are ordinarily prerequisites for the formation of fog. One of the great hazards associated with fog is a lack of visibility.

An aqueous solution of sodium sulfide is allowed to react with an aqueous solution of magnesium chloride.The complete ionic equa

dimulka [17.4K]

Answer: The complete ionic equation contains $2Na^{+}(aq.)$ ions

Explanation:

Complete ionic equation is defined as the equation in which all the substance that are strong electrolyte are present in an aqueous are represented in the form of ions.

The chemical equation for the reaction of sodium sulfide and magnesium chloride is given as:

$Na_2S(aq.)+MgCl_2(aq.)\rightarrow 2NaCl(aq.)+MgS(s)$

Ionic form of the above equation follows:

$2Na^{+}(aq.)+S^{2-}(aq.)+Mg^{2+}(aq.)+2Cl^{-}(aq.)\rightarrow MgS(s)+2Na^+(aq.)+2Cl^-(aq.)$

The complete ionic equation for the above reaction follows:

$2Na^{+}(aq.)+S^{2-}(aq.)+Mg^{2+}(aq.)+2Cl^{-}(aq.)\rightarrow MgS(s)+2Na^+(aq.)+2Cl^-(aq.)$

Hence, the complete ionic equation contains $2Na^{+}(aq.)$ ions
